Simple: Biodegradable phone cases degrade naturally instead of polluting our environment.
So far, cell phone cases are made of plastic. Plastics such as TPU or PC offer many positive attitudes such as high resistance, high flexibility and a long durability. However, this durability is a problem when the cell phone case has reached the end of its life. Plastic needs about 50 years until it is completely rotten.
Recently, plastics can also be made from the material PLA (polylactide). This material is made from sugar and has the positive property that it can be fully composted within 18 to 24 months in an industrial composting plant.
